FUNGI IN CRAWL SPACES

The problem with crawl spaces ventilated by outdoor air is that they get
too little heat during the winter, resulting in them staying cold during
most of the summer.

When the warm outdoor air enters the crawl space during the summer, it
cools down fast and increases the humidity in the crawl space or in a
worse case scenario condensates.

In such an environment the risk is big for micro-organisms to develop.

If more damp enters the crawl space, e.g. via water leaks, damp that
comes from the ground, walls and others, the risk increases for micro-organisms
to develop there.

There is also a risk that the micro-organisms produce smells that might
spread to the living areas.

DRY CRAWL SPACES

The fact is that almost every third house that has a crawl space has
problems with damp and mould. The problem arises when warm air comes
into the cold space and condensates.

Mould, bacteria and rot fungus affects the indoor environment negatively
and can cause damages that are costly to repair, since this kind of
damage is usually not covered by traditional home insurance policies.

AFFECTED CRAWL SPACES

A modern crawl space is today seen as an unsafe construction since
they easily get damp problems. The problem is a result of seasonal changes
and occur primary in unheated sections of the house such as crawl spaces,
garrets and cold storages areas.

The moisture content can periodically be so high, that bacteria, mould
and other micro organisms begins to develop there. When the humidity
is over 75% they thrive very well.

The yearly average for relative humidity outdoors is ca 80-85%. Therefore
it is important to check the humidity in the crawl space so it does
not become damp damaged, leading to costly renovations.
